Have you noticed that your breast pump is not working as well as it used to, maybe a decrease in suction or changes in your milk expression? Your membranes or valves could be to blame. Missing or worn out pump parts can dramatically affect your pump's suction and overall performance. Depending on how frequently you pump will determine how often you need to change your membranes and valves. If you are a full time pumper, you will want to change your diaphragms every 60 to 90 days. This pack of Evenflo Feeding Replacement Breast Pump Membranes and Valves contain 2 silicone membranes and 2 polypropylene valves so you have extras on hand when you need them. The membranes are tinted to make them easier to find during use and while cleaning. These replacement parts work with all Evenflo pumps, including your Advanced Double Electric, Advanced Single Electric and Manual breast pumps.
To help keep your breast pump working as it should, keep a close eye on these parts and replace them if you see a tear or stretching, or notice a decrease in suction, so you can continue to efficiently express your milk for baby. Keep an extra set of replacement membranes and valves with your pump so you have them when you need them most. All Evenflo replacement parts are 100% free of BPA, polycarbonates, PVC and phthalates and are made of FDA approved food grade material.
